Small-Signal Analysis, Prestressed Analysis, and Harmonic Perturbation Plot Settings
For the plots that incorporate harmonic perturbation, small-signal analysis, or prestressed analysis, additional settings display in a variety of plot windows in an Expression evaluated for list:
Expression Evaluated For
Select an option from the Expression evaluated for list: Static solution, Harmonic perturbation, Total instantaneous solution, Average for total solution, RMS for total solution, or Peak value for total solution. Each option is described below.
See Built-In Operators for information about the operators described in this section.
Static Solution
The expression is evaluated by taking the values of any dependent variables from the linearization point of the solution. This is achieved by wrapping the expression in the linpoint operator.
Harmonic Perturbation
If Harmonic perturbation is selected, the Compute differential check box is also available. If the check box is not selected, the expression is evaluated by taking the values of any dependent variables from the harmonic perturbation part of the solution.
If the Compute differential check box is selected (default), the differential of the expression with respect to the perturbation is computed and evaluated at the linearization point. This is achieved by wrapping the expression in the lindev operator. For expressions that are linear in the solution, the two options are the same.
Total Instantaneous Solution
The expression is evaluated by adding the linearization point and the harmonic perturbation and taking the real part of this sum. This is achieved by wrapping the expression in the lintotal operator. The phase and amplitude of the harmonic perturbation part can be set in the corresponding data set.
Average for Total Solution
This is the same as evaluating for Total instantaneous solution and then averaging over all phases of the harmonic perturbation. This is achieved by wrapping the expression in the lintotalavg operator.
RMS for Total Solution
This is the same as evaluating for Total instantaneous solution and then taking the RMS over all phases of the harmonic perturbation. This is achieved by wrapping the expression in the lintotalrms operator.
Peak Value for Total Solution
This is the same as evaluating for Total instantaneous solution and then taking the maximum over all phases of the harmonic perturbation. This is achieved by wrapping the expression in the lintotalpeak operator.
